Toyota Granvia unofficial owners club

This site is dedicated to the Toyota Granvia, a luxury four-door people carrier (MPV) available in the UK as a grey market import from Japan. If you have general or mechanical questions about your Toyota Granvia, this is the place for you.

Thank you for the suggested modified wheel sizes.Was considering larger diam. wheels, not so much for looks, but more as an overdrive, as the 3 ltr appears to have enough surplus powerand am not using it to pull trailers.The MPG appears to be a sensitive point on these cars and reducing say your revs by 10% should make a difference,trying to stay around the max torque of 2000rpm.Better watch my odometer.

This thread is over 2 years old but I'm looking for advice on larger wheel/tyres for a Granvia diesel 4WD.My 1997 Granvia 4WD (only travelled 69,000 kms!) is geared so that 2100 rpm maximum torque corresponds to ~90kph. This means at 100 kph highway speeds the engine is doing close to 2600 rpm which impacts pretty heavily on diesel consumption.

Firstly are the higher profile tyre options all going to fit (i.e. not rub) with the stock +29mm offset?Are there likely to be any significant handling/stability issues with 15" or 16" and higher than stock 75 or 80 profile tyres?

My leaning is towards the 215/80 R15 tyres so I'm gaining 5.4 kph @ 2100rpm but don't have to change out the very good condition existing 15" steel rims. Has anybody installed 215/80 R15 tyres on their 4WD Granvia? Will they fit? I know the 215/75 R15 tyres fit as a friend with a Regius has these.I'm concerned that the higher 80 profile tyres lifting the entire van 20.5mm (0.81") may result in poor cornering as these are already a big heavy van.

We fitted new 225/75 R15 snow tires on the 1995 Granvia AWD Diesel van and it did rub agaist the plastic splash guards when making sharp turns when parking.Normal driving they work well. As for the higher center of gravity, not much affected adversly, but then the van width is rather narrow compared to its height and one can feel the difference with the lower suv.It does bring down the rpm, but can´t remember the details. I do think I commented on this in an earlier comment. I think it was about 4-5%.The van has more than enough power to handle it, but obviously going uphill it looses power and I do down shift before the automatic does.

Did the same on the 2000 Granvia Cruising Selection AWD 3.4ltr gasoline, again the snowtires rub against the slashguard when parking, so removed those. Had no problems with the all season tires of same size. The diesel gets a little better mpg or 8-9km/ltr at around100-110km/hr, between sealevel and 4500ft, while the gasoline van uses somewhat more,which is quite a bit for a small van. Our Dodge 4x4, 3/4 ton p/u truck with a 5.9ltr Cummins, net weight 3100kg gets about the same mpg.grandad
